The implementation is to take place through collaborative cooperation between internal, industrial and amateur radio participants. This activity will consolidate the requirements of the amateur and commercial satellite industry, weigh up different payload options, address the future user segment, develop scenarios for the financing, procurement and operation of such a payload, and investigate possibilities for placement on geostationary platforms. This past weekend, AMSAT-DL released their proposal. AMSAT-UK, along with the British Amateur Television Club, AMSAT-NA, and the UK Microwave Group previously made a separate proposal <https://www.amsat.org/wordpress/wp-content/uploads/2023/12/ESA-GEO-proposal…>. AMSAT-DL's proposal <https://amsat-dl.org/wp-content/uploads/2024/03/AMSAT-DL_Proposal-Geo-Paylo…> is written by the authors Kai Siebels, DH0SK and Matthias Bopp, DD1US. The proposal takes into account the technical requirements and needs of radio amateurs. Various aspects such as orbit, satellite and platform as well as payload are taken into account. Among the possible orbits such as MEO, HEO and GEO, the GEO orbit has proven to be the most suitable due to the extensive experience with OSCAR-100. A good compromise for the orbit position would be at ~43 degrees West to also support Eastern European countries and most of North America. A payload for amateur radio should allow the greatest possible scope for experiments on different bands. Six bands could be used for the uplink to enable experiments with different frequencies. The main uplink band is the 13 cm band, the main downlink band is the 3 cm band. All proposed band / NB transponder combinations can be implemented at the ground station with very reasonable effort. A dedicated AMSAT (Amateur Radio) mission based on an ESA-supported Micro GEO provides opportunities for several additional experiments that support AMSAT’s education, science and development goals to inspire young people with amateur radio technology. Finally, such a mission could also provide an excellent platform for disaster/emergency communications directly via the GEO satellite transponders. Micro GEO and QO-100 Micro GEO satellites are a new class of small geostationary communications satellites. They are around a tenth of the size of traditional geostationary satellites and typically measure just one cubic meter. This smaller size makes them significantly cheaper to manufacture and launch, allowing satellite operators to offer customized regional services or gap fillers that would not be financially feasible with large satellites. The amateur radio payload “QO-100” on the Es’hail-2 geostationary satellite, is a groundbreaking platform for the amateur radio community as it represents the first geostationary payload for amateur radio. The exemplary collaboration between AMSAT-DL, QARS and commercial partners on this project to integrate amateur radio payloads into a commercial satellite is a sign of the ongoing cooperation between the amateur radio community and the commercial space industry. This synergy can open up new avenues for amateur radio projects in space. QO-100 serves as a bridge between traditional approaches and new possibilities, while remaining firmly rooted in the principles of amateur radio. Its presence in geostationary orbit is a triumph for the amateur radio community and a sign that amateur radio can continue to play an important role in the exploration and use of space. SYNCART 2.0 on the Heinrich Hertz satellite The Heinrich Hertz Satellite Mission (also known as H2Sat) is a national, geostationary communications and research satellite. It was planned by the Space Agency of the German Aerospace Center (DLR) on behalf of the BMWi as part of the German government’s space strategy and serves both independent payloads (“hosted payloads”) and the in-orbit verification (IOV) of technologies as well as for research purposes. In July 2012, AMSAT-Germany (AMSAT-DL) proposed an amateur radio payload on the Heinrich Hertz satellite with the name “SYNCART 2.0” <https://amsat-dl.org/wp-content/uploads/2024/03/Projektvorschlag-HeinrichHe…>. This was a further development of the transponders of the P3-D AMSAT-OSCAR-40 satellite in the X and K amateur radio bands and a beacon in the 76 GHz band. The objectives of the amateur radio payload were as follows: - Development of the geostationary orbit for the amateur radio service - Communication resource for emergency and disaster radio (with low-power, small, simple technology) - In-orbit verification of SDX technologies - Promoting the spread of microwave technology - Gaining new insights by studying propagation conditions in the 76 GHz band for satellite applications - Provision of a signal for the calibration of antennas, converters and receivers, in particular for radio astronomical applications - Stimulating the acquisition of scientific and technical education, especially among schoolchildren and young people, by providing a permanently available satellite resource, e.g. for use in teaching, research and education - Acquisition of concrete knowledge and experience with satellite technologies and corresponding research opportunities in order to provide the space industry with highly qualified specialists. The concept aimed to make efficient and effective use of any remaining H2Sat capacity. The Heinrich Hertz feasibility study was completed in 2010. Planning phase B was carried out from 2011 to 2013. In July 2012, AMSAT-DL submitted its proposal for an amateur radio payload. Unfortunately, important positions on the antenna deck and with the payloads were already occupied at this point. There was also an approach for a Ka/Ka relaying transponder, but its use would have been limited to two small spot beams to northern Germany and southern Germany. At the time, this did not seem justifiable to our members and the amateur radio community in terms of the cost/benefit ratio. After it became clear that an amateur radio payload on the Heinrich Hertz satellite in the proposed form was not feasible, the proposal was finally withdrawn in September 2012. Miraculously, however, a new window opened just a few months later! Initial talks and contacts were held as early as December 2012, which ultimately led to an amateur radio payload on the Es’hail-2 satellite, also known as Qatar-OSCAR 100 or QO-100. Es’hail-2/QO-100 was launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. This project is a joint initiative of the Qatar Satellite Company, the Qatar Amateur Radio Society and AMSAT-DL. The satellite was built by Mitsubishi Electric Corporation in Japan and is located in a geostationary orbit at 26° East.

The ERMINAZ mission is a syndicated multi-PocketQube mission with a total of 7 PQs under the leadership of AMSAT-Germany, which also holds the launch contract with RFA under DLR support. The project is in collaboration between AMSAT-DL, AMSAT-EA (Spain), ESERO-Germany (Bochum Observatory) and Libre Space Foundation (Greece). The mission is to promote, advance and develop knowledge about space and amateur radio. ERMINAZ-1U & ERMINAZ-1V will transmit telemetry, images, provide a digipeat/store/forward functionally to all radio amateurs worldwide. ERMINAZ-1U will operate in the UHF amateur satellite band, while ERMINAZ-1V will operate in the VHF amateur satellite band. Only non-proprietary, open source and documented protocols, accessible to radio amateurs, will be used. This includes CCSDS telemetry, CW beacon, SSDV images, digipeater, AX.25 und possibly other modes. Telemetry and sensor data from radiation sensor and triaxial accelerometer / gyroscope / magnetometer will allow any radio amateur to participate by extending his knowledge about space. In addition, a digipeater and store & forward function will allow licensed radio amateurs to use ERMINAZ-1U/1V as a relay to communicate with other radio amateurs worldwide. The mission will conduct several experiments with different types of modulations, bandwidths, data rates and framing schemes: GFSK with data rate from 9600 up to 19200 GFSK with data rate from 9600 up to 19200 bits/s GMSK with data rate from 9600 up to 19200 bits/s BPSK with data rate from 9600 up to 19200 bits/s QPSK data rate from 19200 up to 38400 bits/s Frames will using three different framing schemes configurable upon the mission requirements: CSDS (residual or suppressed carrier) or IEEE 802.15.4 (preamble, sync) or AX.25. Planning a launch by RFA-Rocket Factory Augsburg AG from SaxaVord Spaceport into a 500km polar orbit not earlier than August 2024 together with UNNE-1 (HADES-E) and MARIA-G (HADES-F) from AMSAT-EA and QUBIK 5 from LibreSpace. Up and downlinks on 145.965 MHz (ERMINAZ-1V) and 435.775 MHz (ERMINAZ-1U) have been coordinated. *[ANS thanks AMSAT-DL and the IARU for the above information]* ------------------------------ LoRa Digipeater Satellite from the U. S. Naval Academy Scheduled for 2025 Launch A 3U CubeSat. USNA-16 will provide UHF LoRa digipeater service to the amateur radio service. Additionally, USNA-16 is a university-student educational amateur radio mission. It will test a modular CubeSat design and integration, as well as the efficacy of student-designed passive magnetic pointing scheme for S-band operation. INCHsat payload will provide UHF service to the amateur radio service. In addition INCHsat payload is a university, student lead, educational amateur radio mission. It will test custom designed and built components. Specifically it will test a custom on-board computer, a custom radio (based off the OpenLST), a custom motherboard, and a custom antenna deployment system. USNA-16 is a student educational amateur radio mission. It will test a modular CubeSat design and integration, as well as student-designed passive magnetic pointing scheme. TT&C will occur at UHF (437.235 MHz, will be designated as UHF-TTC in this document) and data downlinks will occur at 2.42GHz, both within the amateur bands and both using the LoRa protocol. This will be the first satellite launched by USNA using LoRa, with a potential future application of APRS over LoRa. USNA-16 will also provide UHF LoRa digipeater service at 437.235 MHz to facilitate communication between amateur operators. INCHSat is a student educational amateur radio mission built by students at the University of Maryland, including the licensee, KC3VBJ. There are no paid employees. The main goal is to enhance the aerospace skills of students in a professional context. The students are learning about satellites and space mission development and space communication by designing, building, and launching a payload onboard a cube satellite. The payload consists of a custom onboard computer, the radio, basic sensors, motherboard, and an antenna deployment system. Communication with the payload will be performed on the 437 MHz band from a ground station that will be constructed on the UMD campus. This payload radio (437MHz) will be designated as UHF-PLD in this document. USNA-16 will have a LoRa digipeater to serve the amateur satellite community. LoRa offers low-power beyond-line-of-sight digital UHF communications to the amateur community. Additionally, USNA-16 is a student educational amateur service mission that communicates on amateur frequencies. This will be the first satellite launched by USNA using the LoRa protocol, with a potential future application of APRS over LoRa. INCHsat payload is for the purpose of the training of UMD students in the construction and development of aerospace components. It also tests the components that we have developed on our own for future missions and research purposes with no commercial benefit. INCHsat payload will have a radio based on the open source OpenLST from Planet Labs to serve the amateur satellite community. INCHsat payload is also a student educational amateur service mission that will be communicating data obtained on amateur frequencies. Pending the mission success the code and schematics of the components used will be published as a cheaper alternative for amateur teams looking to launch a cube satellite. Proposing these downlinks UHF-TTC, 437.235 MHz, U/D, LoRa protocol @ 3.42 kbps data rate and on S-band, 2.42 GHz, LoRa protocol @ 60 kbps data rate.

On October 19, 1989, a monstrous X13 class solar flare triggered a geomagnetic storm so strong that auroras lit up the skies worldwide the following day. Had you been flying around the Moon at that time, you would have absorbed a dose that would most likely kill you within a month or so. This is why the Orion spacecraft that is supposed to take humans on a Moon fly-by mission this year has a heavily shielded storm shelter for the crew. But shelters like that aren’t sufficient for a flight to Mars. To obtain protection comparable to what we enjoy on Earth would require hundreds of tons of material, and that's simply not possible in orbit. The primary alternative—using active shields that deflect charged particles just like the Earth’s magnetic field does—was first proposed in the 1960s. Today, we’re finally close to making it work.

APRS Via ISS
by Erik Eitel 30 Mar '24

30 Mar '24

I’m pretty sure I made my first APRS via ISS contact today, which is fairly exciting for me…. I’m using a Yaesu FTM-400 connected to my M2 LEO pack. A few questions for those that are more familiar: I sent CQ SAT FN20 as my message, is this appropriate or is there a bette format? I expected to receive an automated reply from RS0ISS, but I did not. Any idea as to why not? I received a direct message from another operator, to which I replied. His was the only message that I decoded although I heard many other transmissions. Any idea why I only decoded one? I went to aprs.net <http://aprs.net/> and I see all of the messages there, including mine. Wondering if there are any resources for learning about this more, especially using the FTM400 APRS and satellite. Thanks for the help! 73 Erik K2ERK - FN20

The ARISS digipeater is on 145.825 MHz. I often use the terrestrial APRS frequency of 144.390 to test a Soundmodem setup. I'm in the Chicago area and there are always lots of packets. I don't need to wait for the next pass to find out if it works.

Setup to receive packet from ISS
by Derrick Lau 30 Mar '24

30 Mar '24

Hello all: I am running a Windows 10 laptop with the following SDR setup: RTL-SDR Blog v3 SDR# with the RTL-SDR Blog v3 drivers copied into the folder. Since the SDR# download said it was x86, I copied the x86 RTL-SDR Blog drivers into its directory. VB-Audio virtual cable. SoundModem UISS SDR# is configured so its audio out goes to VB-Audio virtual cable in. SoundModem is configured so its audio in reads from VB-Audio virtual cable out. UISS is set so that it uses SoundModem, not AGW Packet Radio. When I start SDR # to listen on the ISS packet download frequency (I think 430.55 MHz), and point my antenna in the general direction of the ISS, nothing appears in the main panel of the ISS application. Is there something I missed? Thanks, Derrick

If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-03-29 20:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-03-29 20:00 UTC. (***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.
